Only after walking into the cave did Gu Nuan Nuan realize how unexpectedly large it was inside. It wasn't damp or dark like she had imagined, either. She marveled silently. Soon, she noticed that in addition to the light from the entrance behind her, a glow was also filtering in from up ahead. This reassured her; the cave wasn't sealed off. 'I wonder if there's another exit,' she thought.
She suppressed her curiosity and walked a bit farther before finally seeing the subterranean river Cao Cao had mentioned. The river wasn't large—it looked to be no more than five or six square meters in area—but the number of fish inside was shocking. They were packed so tightly, jostling against one another, that they could barely swim.
"A Fish Spring?"
